Description

IC1396A - Elephant Trunk Nebula[b]...................................................[/b]Located in the constellation Cepheus, at a distance of about 2400 light-years from Earth, IC1396 is an emission nebula with a diameter of over 100 light-years, the gas that forms it being crossed by cosmic dust filaments, more or less dense, these blocking the light emitted by the nebula, thus creating various dark shapes that contrast with the glow of the gas. One of these shapes represents the main subject of the attached image, being at the same time the only one that received a popular name, besides the catalog name. This is the Elephant's Trunk and represents an irregular column of cosmic dust that stretches over a distance of about 20 light-years, being also the main region of the nebula where the new stars are born.In terms of astrophotography, although it is a well-known nebula, the Elephant Trunk is a target with a medium degree of difficulty, with long exposures and the use of narrowband filters being necessary to end up with a decent result.
